Voltz

Hello, I've just started playing voltz. I have 20 mods on my voltz 1.4.7 and MCforge 6.6.0.497. Since I am on mac, my technic launcher doesn't work so, I run voltz on MultiMC launcher. Apparently, I cannot log onto any servers because I'm missing so and so mods. Please help me. If you have any suggested servers feel free to comment them
